Instance properties (descriptor on the class) may not define methods
(probably a bug).
I don't understand what you're saying in that last sentence; can you
elaborate?
"verifyObject/verifyClass" is likely not to handle the following
case correctly:

     class I(Interface):
       def m(...):
         ...

     class C(object):
       implements(I)
       m = property(lambda self: lambda ...: ...)

i.e. when a method (declared by the interface) is implemented by a property.
